Third Man RecordsElton John has let slip that he recently recorded a song with Jack White for a new documentary miniseries for the BBC. Titled American Epic, the six-episode program profiles blues artists of the 1930s and features contemporary musicians recording on vintage equipment.

While the legendary pop singer didn’t give many details about the track he made with White, he did reveal the history behind the equipment they recorded on. “I got to use the original machine from 1934 that Bessie Smith and Louis Armstrong recorded on, and I wrote a special song with Bernie [Taupin], and Jack White played on it,” he tells The Hollywood Reporter. “So it went straight to analog. That was a lot of fun.”

White's love of blues music recently drove him to put together a massive box set which includes around 100 sides from the now-defunct label Paramount Records, best known for its recordings of African-American jazz and blues in the 1920s and early 1930s. Titled The Rise and Fall of Paramount Records, Volume One (1917-1927), the package will be available starting November 19 at Third Man Records. A second volume of releases from Paramount Records will be released sometime next year.
